Tungsten Carbide VS HSS （1）

ʻO HSS (pōkole no ke kila kiʻekiʻe) ka mea maʻamau no nā mea hana ʻoki metala i ka wā ma mua. I ka wā i hana ʻia ai ka tungsten carbide, ua manaʻo ʻia he mea hoʻololi pololei no ke kila kiʻekiʻe me ka paʻakikī maikaʻi, ke kūpaʻa maikaʻi loa, a me ka paʻakikī kiʻekiʻe. Hoʻohālikelike ʻia ka carbide cemented i ke kila kiʻekiʻe ma muli o nā noi like a me ka paʻakikī kiʻekiʻe.

Ka hana o ka tungsten carbide

ʻO ka tungsten carbide he micron-sized metala carbide pauka paʻakikī e hoʻoheheʻe a he paʻakikī kiʻekiʻe. Hanaʻia ka mea paʻa mai ka cobalt, molybdenum, nickel, a me nā mea'ē aʻe. Loaʻa i ka tungsten carbide ka mea ʻoi aku ka kiʻekiʻe o ka carbide wela ma mua o ke kila kiʻekiʻe. Loaʻa iā ia ka HRC 75-80 a me ke kūpaʻa maikaʻi loa.

ʻO nā pono o ka tungsten carbide

1. Hiki i ka ʻulaʻula ʻulaʻula o ka tungsten carbide ke hiki i 800-1000 ° C.

2. ʻO ka wikiwiki o ka carbide he 4 a 7 mau manawa o ke kila kiʻekiʻe. He kiʻekiʻe ka ʻoki ʻana.

3. ʻO ke ola lawelawe o ka mold, ana i nā mea hana, a me nā mea ʻokiʻoki i hana ʻia me ka tungsten carbide he 20 a 150 mau manawa o ke kila kila kila.

4. Hiki i ka Carbide ke oki i ka mea me ka paakiki o 50 HRC.

Nā hemahema o ka tungsten carbide

Loaʻa iā ia ka ikaika kulou haʻahaʻa, ka paʻakikī maikaʻi ʻole, ka brittleness kiʻekiʻe, a me ke kūpaʻa haʻahaʻa haʻahaʻa.

Hana HSS

ʻO ka HSS ke kila kila kiʻekiʻe ke kalapona kiʻekiʻe, ʻo ia ka mea kila me ka paʻakikī kiʻekiʻe, ke kūpaʻa ʻaʻahu kiʻekiʻe, a me ke kūpaʻa wela kiʻekiʻe. I ka moku'āina o ka quenching, hao, chromium, hapa tungsten, a me ke kalapona i ke kila kiʻekiʻe-wikiwiki e hana i kahi carbide paʻakikī loa, e hoʻomaikaʻi i ka pale ʻana o ke kila. Hoʻoheheʻe ka tungsten ʻāpana ʻē aʻe i loko o ka matrix, e hoʻonui ana i ka ʻulaʻula paʻakikī o ke kila i 650 ° C.

Nā pōmaikaʻi o ka HSS

1. ʻO ka paʻakikī maikaʻi, ʻoi aku ka paʻakikī, ka ʻoki ʻoki ʻoi.

2. ʻO ka maikaʻi kūlike, hoʻohana mau ʻia no ka hana ʻana i nā mea paʻakikī liʻiliʻi.

Nā hemahema o ka HSS

ʻOi aku ka paʻakikī, ke ola lawelawe a me ka HRC ma mua o ka tungsten carbide. Ma kahi kiʻekiʻe o 600 ° C a ʻoi aku paha ma mua o 600 ° C, e hoʻemi nui ʻia ka paʻakikī o ke kila kiʻekiʻe a ʻaʻole hiki ke hoʻohana.
